Vacating unit at end of lease

[Hai Le]

Rental Property is located in Upstate NY in Oneida County.

I have a tenant who is currently scheduled to have their lease end at the end of February; they will have only occupied the unit for a year at the end of their lease.

I'm not looking to extend their lease and would like to have the unit vacant upon lease end. Do I have to give a tenant a written notice to vacate the unit upon lease end or is a text message fine? I'm located out of state so just wanted to see which is the easier/more convenient way to terminate the lease.
